RT7257DLZSP Product Details

RT7257DLZSP Overview


This harley voltage regulator utilizes the Cut Tape (CT) package for optimized performance. Throughout this voltage regulator, there are 8 terminations. There is a 8-SOIC (0.154, 3.90mm Width) Exposed Pad package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs configured on this voltage regulator 12v. The adjusting voltage regulator generates Adjustable output. This voltage regulator 12v fits the Surface Mount mounting. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. A DC-DC switching regulator such as this one switches at 1.2MHz. The voltage regulator can be operated with a voltage as low as 4.5V as an input voltage. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. The output current of 3A makes dc to dc voltage regulator feature maximum design flexibility. The maximum input voltage of voltage regulator is 18V. This voltage regulator is included in the Switching Regulator or Controllers subcategory. There are 8 pins used for switching regulator operation. In order for this switching regulator to work properly, the output voltage should be at least 800mVV. Using this voltage regulator 12v, you will be able to get the maximum output voltage of 12V.
